Ordo ovarii indole ab omnibus Thalamifloris Disciflorisque facile distinguendus, nec ullis vere affi- 
nis nisi /licineis quze differunt solummodo ovario perfecte septato.  JMeliacee, Rutacee, Aurantiee, 
Humiriacee ab auctoribus nonnullis eum Olacineis eomparatze, multis notis recedunt. Inter Calyci- 
floras, Cornacee Olacineis arete affines differunt tantum ovario omnino infero, Santalacee inter 
Monochlamydeas perianthio simplice, e& genera nonnulla Olaeineas eum his Ordinibus stricte con- 
nectunt. Ovarium ex Miersio in Ieacineis abortu 1-loculare, appendicibus in generibus nonnullis 
obviis loculos abortivos indicantibus. 
FORMJE ABNORMES. 
Caulis brevis subherbaceus in Olacis specie, herbaceus volubilis succo lacteo in Cardiopteride. 
Folia opposita in Zode et Cassinopside, 3-nervia in Erythropalo ; interdum dentata in Pennantia, 
Villavesia, et Cassinopside ; palmato-lobuta in Phytocrenis specie, et interdum in Cardiopteride.
